How to connect an equalizer to a stereo amplifier

Updated February 21, 2017

An equaliser provides custom adjustments of an audio signal across a range of frequencies before the signal goes to an amplifier for driving a set of speakers. Connect an equaliser to an amplifer with a second set of tape-deck jacks and a "tape monitor" function, which sends the audio signal to the EQ and loops it back again to the amp. Making the connections using a pair of stereo cables should take less than ten minutes.

Turn off the power to the amp and the equaliser.

Plug one end of a stereo cable from the "Tape 2 Out" jacks on the amplifier to the input jacks on the back of the equaliser. Use the white plugs for the left audio jacks. The red plugs go in the right jacks.

Connect the second set of stereo cables from the "Tape 2 In" jacks on the amplifier to the output jacks on the equaliser.

Press the power buttons to turn on the components.

Press the "Tape 2 Monitor" button on the front of the amp to send audio signal to the equaliser. Turn off the "Tape 2 Monitor" feature to bypass the equaliser.

Things You'll Need

  • 2 stereo cables with RCA-type, 6.35 mm (1/4-inch) plugs on each end.
